Summary
Constructed in 1972 by the USDA NRCS, this earth dam spans 1,870 feet in length and reaches a height of 32 feet, holding back the waters of the Long Hollow stream. With a storage capacity of 848 acre-feet, this structure plays a vital role in managing floodwaters and protecting the surrounding area.
The dam's design, featuring a buttress core type, is complemented by an uncontrolled spillway and a system of outlet gates, including a slide gate and two uncontrolled gates. Despite its fair condition assessment as of April 2021, the dam remains a key component in the local flood risk management strategy. With a moderate risk rating of 3, ongoing inspections and enforcement by the TCEQ ensure that the dam continues to effectively serve its primary purpose while safeguarding the community from potential hazards.
As water resource and climate enthusiasts explore the intricate details of the Brown Mullin WS SCS Site 1 Dam, they gain insight into the complex interplay between infrastructure, natural forces, and regulatory oversight. With a drainage area of 2.1 square miles and a maximum discharge capacity of 345 cubic feet per second, this dam is a critical piece of the water management puzzle in Texas. By understanding the history, design, and function of this structure, enthusiasts can appreciate the importance of strategic planning and maintenance in ensuring the safety and sustainability of water resources for future generations.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
